150 lbs is huge! Anytime I hit the track I try to keep everything the same as much as possible, that I can control at least. I just ran the 1/4 with about 15 gallons of fuel vs my usual 5, and left my west coast mirrors sticking out. Lazy and rusty I guess. That is a good bit of Mph lost right there, and a smidge on et. I thought about leaving my exhaust in place before running, but wisely ended up dropping it.
